good morning alkisg
people are so happy about the new clients
now i just need to find some solution to remind them every 20 minutes to look around to see if anybody else wants to use the computer
we only have 3 terminals.. and it's really not enough.. but we don't have room but for one more
Well it should be easy to show them a reminder...
I'd just write a script to show them a notification bubble every 20 minutes
ah.. notification bubble.. that's probably one of the lesser intrusion solutions
i was also considering a message in the top bar
|02:31||* johnny is not french|
but.. you can surely greet us in that way
anyone worked with a solar panel ?
can i power up a thin client with that
uhmm.. i don't see why not.. if your solar panel can power it..
probably would want an arm based client
ah i see
much better than anything intel has
even the atom..
it's why almost all the smartphones use arm nowadays
and they can run modern operating systems
linux (and linux distros) run on arm for many of the popular applications
and ubuntu official targets arm as well
so, everything in main must compile against arm
just check your hardwares power usage
Appiah, a standard pc could use from 90 -150W
i've never used solar panels before
the little dual core atom boxes i bought max out at 35W
so i was curious
obviously a cellpone uses much less than that :)
and how much is the arm box? 10 watts ?
check the specific arm box
it really depends
how much else they use
check out beagleboard for a reference implmentation
look up a model you have / going to buy
dobber, the processing power in the phones themselves is now up to 1Ghz
i think the current iphone is 600mhz..?
certainly quite fast enough to handle most things
well, the modern "100-150$ thin clients"
are basicly phones with vga and network ports
dobber, some of the different boards/machines/phones include dedicated graphics processors.. which changes the usage pattern a bit
phones are basically computers that don't have vga ports :)
yeah, that way :)
it's all the same these days really
atm.. most people don't need much more than what 3 years agos computers can do
or more even..
so.. now the mobile stuff is catching up to match
exciting stuff really
|02:49||* johnny pokes alkisg|
alkisg, so.. have you done any more experiments with xmpp? there's some exciting stuff out there coming up finally
that is true johnny
johnny: yeah it'd be nice if we had an xmpp based teacher/student communication program,...
unfortunately I didn't find any easy way to do it, so I used python/twisted/bash instead
alkisg, that's pretty broad
that's the kind of thing i can convince some people to do :)
you just have to spec it out
Specing is easy... as long as there's a chance that it gets implemented
alkisg, also.. google wave is available as a xmpp component nowadays.. in some fashion
i don't recall, but it involves prosody
The best thing to have would be an empathy plugin where the teacher exposes classes and the students join it
sure.. but what do they do the the classes?
..and the teacher can then transmit files to the students, or help them with remote desktop etc
hmm.. you don't seem to far away from that
Most of the functionality is already there; it just isn't classroom oriented
sine the remote desktop stuff is there
and transmit files is there
Right, but you can't tell a teacher to transmit 10 files to 10 students one-by-one
There's no notion of "group" or "classroom" for the moment
a group? well.. there are groups in xmpp
in the buddy list
also.. wouldn't the entire local subnet under the zeroconf look like a group?
obviously that would depend on your network segmentation
Yeah that would work too, in most cases.
the other way, would be to use the shared groups functionality of xmpp
so, you assign it at the sys admin level
instead of adhoc based on who's in the classroom
that's another valid approach
Well the fact is that empathy doesn't support sending files to multiple recipients etc... so someone knowledgable would have to take up on this
so.. then what? you're just left with a ui problem with the lack of "Send to Group" ?
sure.. but that's only one issue
what are the rest
if you write this down.. i will bear down on some people to get it done
E.g. execure remote commands...
not necessarily next week
but.. hmm.. wasn't there this dbus based thing that was like apple script
I.e. it could be something like an italc replacement, where the teacher manages his students
then you could just send those around
dbus doesn't work between different pcs currently
sure.. but i meant sending them one of these scripts to execute
which are mapped to dbus verbs and nouns
And if xmpp is going to be used as the backend, there's no point in limiting it to the local network
of course not
So I don't think dbus would be required in the implementation...
i wonder if that project is still around
dbus for the "execute commands"
|02:58||* johnny will brb|
had to do some stuff
hopefully grub evolves enough of a usb driver to do the same..
pendrivelinux sure has alot more posts nowadays :)
alkisg, .. portable virtualbox!
johnny: thanks, that looks good. Did you read how it works? Does it copy itself just below 640Kb and change the conventional ram reported by the bios?
that surely sounds like a great way to use my tools on somebody elses computer
alkisg, no. i was just browsing and noticed it
i was going to ignore that aspect for now, and just looking for a distro that does what i want
i know the portable apps stuff for win is pretty good
would like to see that merged in with an iso app runner too
something that tracked the various livecds and kept it up to date
hmm.. it's just too bad about the filesystem requirements tho..
since windows doesn't have an ext2/3/4 native driver :(
hmm.. another solution might be to use wubi and portable virtual box..
that is.. until linux can boot to a virtual box disk image natively..
one step closer..
but.. it's windows only
|03:33||* johnny thinks|
that one even sets up the portable virtual box!
now.. does such a thing exist for linux..
|03:36||toscalix has joined #ltsp|
|03:37||* johnny doubts there will be a portable colinux ever|
alkisg, ! http://liveusb.info/dotclear/index.php
that's exactly what i was looking for i think
currently waiting for it to translate from french
ah.. it looks like they kinda went a bad way in implementing it.. it completely requires ubuntu :(
very hard coded

hello all - setting up ltsp 5 on ubuntu 10.04. server is amd64. client i386. Some workstations the client locks up after putting up the desktop background. Others it works fine. Any ideas
gibby i think fly23 has this same problem
gibby: do you get thrown back to the login-manager?
no - just hangs. no mouse movement or icons or menus
hm, after the login, or while ldm should load?
ok, my stations won't come so far
my stations freeze before ldm ;)

seems to be an xserver issue. When I use vesa it boots into desktop fine but at low resolution. resolution setting in lts.conf made no difference. when I removed XSERVER back to same problem. How would I find out which driver it is using?

thunsucker: I got my 9.10 box stable by completely gutting and rebuilding the network authentication system....2 hard days of work.
My 9.04 (formally my main termserver due to stability) is still highly unstable, and I don't know why. Probably need to reformat it.
So, basically Windows strikes again...never trust anything to Windows....Especially applicable to ones authentication system (AD).

Is it unusual that there's no /etc/X11/xorg.conf on the terminal as in mentioned on p. 25 of the LTSP Admin Guide?
atkuepker: the terminal should never have an /etc/X11/xorg.conf
if you configure something, it creates a /var/run/ltsp-xorg.conf
ah, so the docs are off slightly. ok.

setting up a test box now for the 2.6.34 kernel
nomodeset and i915.modeset=false failed
Is it false or 0? Did you google it?
2.6.34 is going to be a tough sell for production environments though. Not looking forward to selling that idea to the IT Director.
I think that driver was more stable in 9.04, maybe you could stick to that until it's stable for 10.04 again
after all the articles I've read about Jaunty's Intel video tribulations, it's rather sad if 9.04 was more stable than 9.10.
I'm still doing some testing here, so I'll play with it further. Tough to determine success when the soak threshold for whether it's working is up 2 business days tho.
It was for a laptop with intel 855 that I have. Karmic and Lucid had problems with it. Now with 2.6.34 it's a little better, but it's still worse than in 9.04.
thankfully I have a few boxes to play with now. Gives me the willies trying to sort this stuff out on a production network.

i can't use any of the fonts in t1-xfree86-nonfree or ttf-xfree86-nonfree even after i have installed them on lucid. Even tried installing maually from the font files. They continue to not register with xlsfonts.
